Step 5: Record the agent with the state
The agent's name and address go into the Certificate of Organization Limited Liability Company when you form. To switch later, file a change with the Idaho Secretary of State.
The annual report (no fee, every year, due last day of the entity's anniversary month) is where Idaho sees your agent details; state notices about it go to the registered agent.
State amounts come from Idaho's official schedules (see References). The three-year state line adds the filing, the reports due in years two and three and any yearly minimum tax.
